SHOCK-ABSORBER FOR TYPE-WRITERS.

Application filed May 24, 1917. Serial N 0. 170,753.

Writers, of which the following is a specification.

The present invention relates to a supporting base or stand fortypewriters, and aims to provide a device of that character of suchconstruction as to absorb the shocks and deaden the noise of thetypewriter.

It is also the object of the invention to provide such a device which isextremely simple and inexpensive in construction, being readilymanufactured cheaply from strips of metal, and being foldable forcompact shipment or storage, as well as being adjustable to accommodatevarious typewriters.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawing, wherein Figure1 is a perspective view of the de v1ce.

Fig. 2 is a plan View thereof in folded po sition.

Figs. 3, d and 5 are sectional details on the respective lines 3-3, L4cand 55 of Fig. 1.

In carrying out the invention, there is provided a pair of supportingbars or strips 1 constructed of resilient; material, and having theirterminals bent back downwardly to provide feet 2 and resilient loopsbetween said feet and the body portions of the bars 1, whereby the feetin being supported on the table or other support, will permit the bars 1to yield and thereforeabsorb the shocks to which the typewriter, whichis supported by the bars 1, is subjected.

In order to adjustably connect the bars 1 and permit them to be adjustedtoward and away from one another to accommodate varlous typewriters, andto permit the bars to be brought together to fold the device, shortlinks 3 are pivoted by means of screws 4: or otherwise upon the feet orterminals .2 of the bars 1 and relatively long crossed links 5 havetheir ends pivoted, as at 6, to the other ends of the short links 3, andthe links 5 where they cross one another at the intermediate portionsthereof are also pivoted together, as at 7. The links 3 and 5 provide amodified form of lazy tong connection between the bars 1, to enable saidbars to be moved toward and away from one another, and to be broughttogether, as seen in Fig. 2, in which position of the parts, the shortlinks 3 swing over the feet 2 within the loops of the bars 1, and thelinks 5 swing between the links 3 and bars 1.

Convexed washers 8 are disposed upon the screws 4, said screws havingtheir heads lowermost below said washers and their threaded endsengaging the links 3, and felt or other suitable pads or cushions 9 areseated in the washers 8 and are secured therein by the screws 4:, asseen in Fig. 5. These pads 9 seat upon the table or other support, andserve to cushion the shocks and prevent the device from slipping. Thefeet 2 are thus supported by the pads 9 above the surface of the table,thus permitting said feet 2 and loops of the bars 1 to spring.

Mounted upon the'bars 1 are the cups 10 and 11 for receiving and holdingordinary rubber cushions or feet of the typewriter. The cups 10 at oneend of the present device or frame are mounted slidably upon the bars 1for purpose of adjustment, and for this reason they are secured uponclips or slides 12 movable upon the bars 1. The cups 11 are securedrigidly upon the bars 1 at the other end of the frame, by means ofscrews 13 engaged downwardly through the bottoms of the cups 11 andthreadedly engaging the bars 1. Cushions 14 of felt or other suitablematerial are disposed in the cups 10 and 11 to further cushion theshocks, and the cushions 14 and cups 11 are held therein underneath theheads of the screws 13.

The bars 1 can be readily adjusted to bring the cups 10-11 at theopposite sides into the proper line, and the cups 10 can be shifted onthe bars 1, whereby all of the cups Copies of this patent may beobtained for arein position to be engaged by the pads or feet ofthe'typewriter.

Having-thus described the invention, what is claimed as new is y Asupporting base for typewriters including parallel resilient bars havingdownwardly and inwardly tlirned terminals con- 'stituting yieldablefeet, cushions carried by anddepending from said feet, means upon eachbar and adjustable relative to each other upon the bar for engaging andholding the typewriter, crossed pivotally connected links between thebars, and short link connections between said crossed links and therespective feet.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
